When playing a 48/24 .wav file (48 kHz and 24 bit depth) Volumio 2.041 display gives 48kHz and 32 bit as values. Not a big issue, but it’s not the correct value.
Likewise, all 24-bit WAV files are displayed as 32-bit, no matter the sampling rate.
Not a big deal, but this incorrect WAV file bit depth is still present in 2.411 version.
I can confirm this, you can download a (test) sample here (by Blue Coast Records) for free to test.
If I test this, the following objState is returned:
{"volume":"40","repeat":"0","random":"0","single":"0","consume":"0","playlist":"15","playlistlength":"1","mixrampdb":"0.000000","state":"play","song":"0","songid":"7","time":"0:226","elapsed":"0.000","bitrate":"0","duration":"226.126","audio":"96000:32:2"}Which means the 32 bit comes from the MPD result, I can dig code, but I can’t seem to retrace this particular ‘bug’.
As it appears the error occurs before we hit ‘app/plugins/music_service/mpd/index.js’
The problem is still outstanding in version 2.632.
However it seems to affect MP3 files, while the bit depth of WAV files is reported correctly.
